Indian Army Agniveer Mock Test - 7 - CDS MCQ

The difference between the exports from the Companies X and Y during the various years are:

In 1993 = Rs. (80 - 30) crores = Rs. 50 crores.

In 1994 = Rs. (60 - 40) crores = Rs. 20 crores.

In 1995 = Rs. (60 - 40) crores = Rs. 20 crores.

In 1996 = Rs. (70 - 60) crores = Rs. 10 crores.

In 1997 = Rs. (100 - 80) crores = Rs. 20 crores.

In 1998 = Rs. (100 - 50) crores = Rs. 50 crores.

In 1999 = Rs. (140 - 120) crores = Rs. 20 crores.

Clearly, the difference is minimum in the year 1996.

8% of 800 for 4 years + 6% of 800 for 4 years = 64 x 4 + 48 x 4 = 256 + 192 = 448. However, we do not know the rate of interest applicable in the 5 th year and hence cannot determine the exact simple interest for 9 years.

Work equivalence method:
30 × 5 × 16 = 20 × 6 × n
Gives the value of n as 20 days

250 / 5 = 50

So Option C is correct

52254 – 3512 + 119 = 48861

So Option B is correct

original number – 10x + y
(10x + y) – (10y + x) = 27
9(x – y) = 27
x – y = 3
y/x = 1/2
x = 2y
y = 3, x = 6 →63

Number = LCM (12, 17, 35) + 6 = 3780 + 6 = 3786

Answer – b) decrease 4.32% Explanation : Let initially seats are 100 and price of each seat is 100, so total initial revenue = 10000
now, seats are 92 and price of each seat = 104, so total revenue = 92*104 = 9568 so percent change in revenue = (432/10000)*100 = 4.32 decrease

A gets 10% of the profit for managing the business = 10% of 9600 = Rs. 960
Profit remaining = 9600 - 960 = Rs. 8640
Ratio in which they will share the remaining profit = 12 : 20 = 3 : 5
A's share = 960 + (3/8) 8640 = Rs. 4200

Let the numbers be x, y and z.
x + y + z = 98
Also, x : y = 2 : 3 and y : z = 5 : 8
Therefore, x : y : z = 10 : 15 : 24
Let x = 10k, y = 15k and z = 24k
Then, 10k + 15k + 24k = 98 
⇒ k = 2
The numbers are 20, 30 and 48.
Hence, second number is 30.

Let SP be Rs. x.
Then, CP = Rs. (13/15)x
Receipt = 112% of Rs. x
= Rs. (28/25)x
Gain = Rs. [(28x/25) – (13x/15)]
= Rs. 19x/75

Lateral surface area (L. S. A.) = 2πrh
Total surface area = (T. S. A.) = 2πr(r + h)

5h = 3h + 3r
2h = 3r

r² = 196
r = 14 m

= 12,936 cubic m

Triangle ABC has area 
Triangles ABW, WBX, XBY, YBZ and ZBC have equal bases and altitudes, so the area of each of these small triangles is 1/5
Similarly, triangles ADW, WDX, XDY, YDZ and ZDC each have area 9/2.
Thus, the shaded region has area 

Answer: b

Exp: The army was first formed in 1942 under Mohan Singh, by Indian PoWs of the British-Indian Army captured by Japan in the Malayan campaign and at Singapore. An armed force formed by Indian nationalists in 1942 in Southeast Asia during World War II. Its aim was to secure Indian independence from British rule

India is not only the largest producer but also the largest exporter of mica in the world. Andhra Pradesh is the largest producer of mica (Geography of India by Majid Hussain). It is the second largest producer and exporter of tea after China in the world.

The Jan Vishwas (Amendment of Provisions) Bill, 2023, was introduced in the Lok Sabha by Commerce and Industry Minister Piyush Goyal. The bill aimed to address the criminalization of minor offenses by proposing amendments to various acts. After being referred to a Joint Parliamentary Committee, chaired by Mr. P.P. Chaudhary, the committee submitted its report on March 17, 2023, which formed the basis for further amendments and approval by the union cabinet.

The Ministry of Statistics and Programme Implementation (MoSPI) will oversee the review of surveys conducted by the National Statistical Office (NSO) after the replacement of the Standing Committee on Economic Statistics (SCES). The new committee, called the Standing Committee on Statistics (SCoS), will have an expanded mandate to review the framework and outcomes of all surveys conducted by the NSO. This move aims to ensure effective oversight and improvement in the statistical processes and data quality in the country.

The density of steel usually ranges between 7.75 and 8.05 g/cm3 and the density of mercury is 13.534 g/cm³. Mercury is denser than steel this will mean that the buoyant force is large enough to float the steel ball. Different materials usually have different densities, so density is an important concept regarding buoyancy, purity and packaging.

An audio frequency is characterized as a periodic vibration whose frequency is audible to the average human. It is the property of sound that most determines pitch and is measured in hertz (Hz).The generally accepted standard range of audible frequencies is 20 to 20,000 Hz, although the range of frequencies individuals hear is greatly influenced by environmental factors.

The atomic nucleus consists of nucleons—protons and neutrons. Protons and neutrons are made of quarks and held together by the strong force generated by gluon exchange between quarks.

The hollow space of the middle ear has also been called the tympanic cavity. It is an irregular, laterally compressed space within the temporal bone. It is 44(filled with air, which is conveyed to it from the nasal part of the pharynx through the auditory tube. The middle ear contains three tiny bones known as the ossicles: malleus, incur, and stapes.

Blood plasma is the strawcolored/pale-yellow liquid component of blood that normally holds the blood cells in whole blood in suspension. It makes up about 55% of total blood volume. It is mostly water (93% by volume), and contains dissolved proteins, glucose, clotting factors, electrolytes, hormones and carbon dioxide (plasma being the main medium for excretory product transportation). 

Schistosomiasis, also known as snail fever and bilharzia, is a disease caused by parasitic flatworms called schistosomes.

A detergent is a surfactant or a mixture of surfactants with "cleaning properties in dilute solutiops." These substances are usually alkylbenzenesulfonates, a family of compounds that are similar to soap but are more soluble in hard water, because the polar sulfonate (of detergents) is less likely than the polar carboxyl (of soap) to bind to calcium and other ions found in hard water. In most household contexts, the term detergent by itself refers specifically to laundry detergent or dish detergent, as opposed to hand soap or other types of cleaning agents.

An early-20^th-century form of quackery was the treatment of maladies in a radiotorium. It was a small, sealed room for patients to be exposed to radon for its "medicinal effects". The carcinogenic nature of radon due to its ionizing radiation became apparent later on. Radon's molecule-damaging radioactivity has been used to kill cancerous cells. It does not, however, increase the health of healthy cells. In fact, the ionizing radiation causes the formation of free radicals, which results in genetic and other cell damage, resulting in increased rates of illness, including cancer.

A rectified spirit, rectified alcohol, or neutral spirit is highly concentrated ethanol which has been purified by means of repeated distillation, a process that is called rectification. It typically contains 95% alcohol by volume (ABV). Rectified spirits are used in mixed drinks, in the production of liqueurs, for medicinal purposes, and as a household solvent.

Bauxite is an aluminium ore and is the main source of aluminium. This form of rock consists mostly of the minerals gibbsite, boehmite and diaspore , in a mixture with the two iron oxides goethite and hematite, the clay mineral kaolinite, and small amounts of anatase TiO₂. Bauxite was named after the village Les Baux in southern France, where it was first recognized as containing aluminium and named by the French geologist Pierre Berthier in 1821.
